Wednesday Lunchtime Net Digital Modes

Update: KB7KBH reports response has been weak, and he also finds himself busier than expected, so the digital focus on Wednesdays has been suspended. Plenty of good information below, however, and a future event or discussion is always possible.

Greetings all. Michael W7ALX wanted me to do the Wednesday Lunchtime Net to see if there was any interest in folks wanting to expand their knowledge in Digital, and Satellite Opps. I am by no means an expert, but I’m willing to assist those that are interested. We will have the normal net, then after check-ins we can discuss the digital and Sat stuff.

Here are some examples of radio setup for digital modes.

Kenwood radio link 590G

Yaesu

Icom

Most of the newer Icom radios have a built-in sound card. Other brands may need a SignalLink USB modem.

There are a lot of YouTube videos that will help guide you thru installation and setup for your brand radio.

The WJST-X free software is what most folks use. They have it for Windows, Mac, and Linux.

https://wsjt.sourceforge.io/wsjtx.html. Com ports are the biggest issues some folks have, Me included!

VARA HF is very similar to FT-8 and some of the settings are similar. It again depends on the brand of HF radio you have. I did a lot of trial and error until I got it. YouTube videos are helpful in setup.

Satellite Comminutions

Satellite comminutions can be a challenge. There are a few in the club that work the birds with a HT or two, and a handheld dual band Yagi antenna. You can find tracking software for your cell phones to help with that. Most of the Sats uplink on 2M, and downlink on 440, depends on the satellite. There are Linear sat’s that are SSB, in that case you would need a radio capable of 2M and 440 SSB. The challenge is the Doppler shift. I have a unit called S.A.T from CSN Technologies. It is a standalone unit that can be used on your cell phone (no computer necessary.  It will control the antennas, frequency’s and doppler shift. I have the Yaesu G5500 rotor for azimuth and elevation antenna control.

Anybody interested can come over to my QTH, and see how it works.

“You sure do talk funny.”

Chuck Gerttula W7CRG

I was 17 and the product of having been raised in a small coastal town in Oregon. I loved history, particularly American history and was fascinated with the Civil War (also known in certain regions as the War Between the States or the War for Southern Independence) An organization in Lake Oswego offered student tours to the east coast to visit many of the places where United States history began. I was fortunate to get to go on one of the American Heritage two week tours with 50 or 60 other young students from the Pacific Northwest.

The train delivered us to Washington D.C. and we were ensconced in a hotel with two to four students in a room. The hotel had a cafeteria downstairs and being teenagers we were eager for some breakfast. As I moved my tray down the line I got a serving of hash browns, eggs … and then I arrived at the meat choices. “I think I’ll have the ham,” I announced.

“Yo’all sure do talk funny, honey child! Where yo’all frum?”

Me talk funny? She was the one with the drawling accent! Yes, I had a lot to learn about my fellow Americans. I learned about different ways to speak, different types of food, I was not supposed to use certain drinking fountains or restrooms and I was not to sit in certain seats.

So how does this relate to ham radio you ask? Well, as hams … “We sure do talk funny.” I was asked how to pronounce the word embroidered on my hat … it was my first call sign “KF7WZV”. I smiled and told the checker at Freddy’s it was an inside joke. That aside, we do use a lot of slang, jargon, call it what you may, and it can be confusing to the new and uninitiated.

Therefore, I’ll be a bit of an elmer and explain some of our jargon. An elmer is a mentor. Someone who helps, teaches and explains the technicalities, information and traditions of ham radio.

Roger is a term used to indicate understanding. Many hams will repeat this thus broadcasting “roger roger” which either means they want to fill their transmission so they don’t appear to have little to say, they are talking to a ham named Roger or it is a poor connection and they have to repeat the words to be understood. Roger is often thought to be the same thing as QSL. That is not the case. QSL indicates receipt and was a means of showing an operator had received the message or transmission from another operator. For many hams exchanging QSL cards which confirmed the time, quality and frequency of a contact was an important part of the hobby.

Perhaps this is a good time to explain the “Q” codes were created when CW or code was the primary means of communication. They were universal codes that shortened the message which is nice when you are sending letter by letter in code. It is so much easier to sent QSL than to send “I have received your transmission”. The same can be said for “7 3” which is sending two characters instead of tapping out “It has been nice talking with you and thank you for the contact”.

Have you heard someone say something like, “that is one of the funniest stories I have ever heard, hi hi”? This is another CW usage that has carried over to phone. If you want to laugh on a phone transmission, the microphone will send your laughter. If your transmitter sends dots and dashes how do you indicate laughing? The convention was to send hi hi (…. ..) (…. ..). Why some use this on phone transmissions I can not say; they should just laugh.

Here are some commonly used phrases, many of which started with CW but are now common on Phone:

ragchew a long discussion over any topic or topics

full-quieting your transmission has no background noise

picket fence the transmission has a fluttering to it

kerchunk a short press of the PTT (Push To Talk) often used to see if the radio is getting into the repeater.

boat anchor an old radio, usually tube type and very heavy.

silent key a ham who has passed away

OM used in CW for Old Man which is a ham

YL used in CW for a female operator, a Young Lady

XYL used in CW for wife

DX D for distance and X for unknown (Asian contact is DX)

The Q codes are good examples of CW terms moving into the realm of Phone conversations. Most of these three letter codes are not frequently used on phone but a few are.

QSO is a contact

QRM is interference from other stations or “M Man made”

QRN is interference from static and other “natural N” causes

QSY is changing frequency “I’m QSYing to 14.255 mHz”

QTH is the station’s location “My QTH is Toledo, OR”

QRP designates low power or to lower power

QST A general call for a message to all hams, which fits for the name of the ARRL magazine

ARRL The American Radio Relay League not the Amateur Radio Relay League

CQ A general call to any station that would respond. Amateur lore has many ideas for the origin of CQ, a popular one is it is from the expression “Seek You”.

Perhaps this will help some better understand the conversations both on the air and at an eyeball qso (face-to-face conversation). Perhaps it is unnecessary as you know these terms well. If any of this makes you more comfortable and better to understand your fellow hams – great! Get on the air and communicate with people from around the block to across the oceans!

• Hello, 

• Sky Terry is the NW Regional Emergency Services Director for the Emergency Volunteer Air Corps (EVAC) and also one of the leaders of the West Coast General Aviation Response Plan (WCGARP).

• It’s been well over a decades worth of drills, responses and effort but what we’ve developed together is a aviation based resource tied with ground support and HAM communication that we believe is the juggernaut that can take the worst the planet can dish out and can rise to the occasion to be that life saving critical life line when it’s needed the most.  Below is just one video of one of our past drills.
